[JSC] Do not clean up Wasm Type registry repeatedly
https://bugs.webkit.org/show_bug.cgi?id=322439
rdar://185720499
Reviewed by Yijia Huang.
We are cleaning up Wasm Type registry whenever destroying Wasm Modules.
But this is happening too much. We should batch them by destroying many
Wasm Modules. We put a global flag (becuase Wasm Type registry is
global), and doing clean up when it is set in GC end epilogue / VM
shutdown timing.
